v and it is moreparticularly in the .nature et an improvement upon those processes ot' this kind iat which a proper rate of' velocity is imparted to the current of gas that is to u`n dergo the action ol. the electrical dis'cliargcs,v

the object herebyv being to enable arcs of great lengths to be ,produced ivith'ihe avoidalice ol short circuits.

The object of the present invention is, to cause the electric discharges to ell'ectually spread over the entirevarca between the electrodes, so thatv the available current strength shall be utilized in the most `profitable inanner.

In order to enable a ready comprehension ofv the new processi will hereafter describe it in connection with apparatus adapted for carrying the invention into effect, reference beinghad to the accompanying drawings, in which* views, Fig. 1 being aA side elevation to Fig.

- Like numerals of reference indicate like 40 parts ln the several views. f

Referring more particularly to Figs. l

and 2, l, 1 are two )ipes designed to supply the gas 4to be acted upon to a place at or near the point of' greatest proximity of the diverging electrodes 2, 2. This will be clear from Fig. 2. '.llie openings t5 of such pipes are opposite each other, so that the two jets of gas discharged therefrom iiieet oneanother, the arrangement being such that the Figures l and 2 are two diagianiniatical Specification of Letters Patent.

particles of gas are caused to propagate in' the plane of the electrodes and in such a manner .as tol fill the entire area between them. To such en-d it will be necessary to .So dispose the blast pipes that their median axis lies inthe plane ot" tlieelectrodes, as will be seen from Fig. l.. The outline which the,discharged gas will torni at the place of greatest divergence oi the electrodes is approxin'iately indicated by the'dotted line a.

An auxiliary pipe causes, by means of its current oi' gas ot an approximately high rate ot velocity, the voltaic arcs produced at the point of greatest proximity of the electrodcs 2 to propagate along the electrodes assuiiiing thercbya shape such as shown by the dotted lines l. Alfter having attained a definite length, such, ilor example, as indicatedrby the dotted line l et the circle 3, they break and extinguish.

In some cases it may be advantageous t0 "provide a number of pairs olf. blast pipes in-v stead 0iE one pair only; the arrangement in suol) event will be clear i'ronrFig. 3.

Instead ot' the auxiliary pipe 5 as aid in the described lorination of .voltaie ares,'mag netical means may be arranged to cooperate with -the currents of gas issuing from the blast pipes l, that is to say, act like the auxiliary current of gas above described to elongate the voltaic arcs'by causing them to propagate along the electrodes until they break and extinguish.'

It will be seen Athat the vell'ect of the new process is, to cause the electric discharges to etfcctually spread over the entire area between tlie electrodes, thereby imparting upon the currents of gasl to be acted upon only an approximately low pressure.

lt is to be understood that any suitable const-ruetion'of i. apparatus for effecting the described process may be used, the construetions illustrated being given by way of example only. Y

lVhat I claim is:

The herein described process, consisting in elongatingthe voltaic arcs produced at the place of greatest proximity oi' the electrodes by causing them by suitable means to ropagnte along the electrodes and in pass- In witness whereof I have hereunto signed mg the gas to be acted upon by the electrical my neme this 23rd day of June 1906, in the dischnr es in currents 'of equal quantity presence of two subscribin Witnesses. and ve ocity in inclined direction against HABE@ P'AULINGI,` 5l each other and meeting in the plane of the Vitnesses:
